Goldfish change color for one of two reasons. The first is a lack of sunlight, which ends up retarding the pigmentation cells in the fish's scales that are responsible for color. This causes a fish to become lighter or white in color. The second reason is for a darkening in scale color. This is because due to irritation of the skin the fish's body releases a chemical called leukine which stimulates color pigmentation cells. Especially melanophores (black pigmentation cells) thus causing the fish to have abnormally high amount of black pigmentation.
depends...
they quite often colour with age, as they get older they get greyer (paler)
also a caused by poor health, feeding and water quality
It's all about where the tank is. For example, if you put a goldfish in its tank in a room with no light, it would turn white.
If your fish has changed colour, it's simply getting used to the light change from the shop/supplier to your home.

∙ 14y agoGoldfish develop from their ova as drab, greyish, silvery, sometimes brownish, little fish. As they grow and mature their true colours start to show and they eventually develop into their magnificently coloured adulthood. If given bad water conditions, or poor food, or poor lighting, their colours may fade. I'm sure you will have heard of the expression "Off colour" well in the case of a goldfish it is quite obvious when they are "Off colour".

Can goldfish change colour?
Most goldfish are more orange in color than actually gold. Their name probably originated in the same way they did. Back in Ancient China the Chinese would keep pools of carp. Overtime, they began to notice that certain fish were a kind of shiny gold color instead of the normal, rather dull, color of most carp. They began separating these fish and breeding them thus creating the pet goldfish. Goldfish most likely got their name because, although they weren't necessarily perfectly gold in color, compared to other carp they were truly golden.
